| Abstract: | The effect on infrared optical system caused by temperature variation is introduced. An athermal infrared refractive optical system with three lenses has been designed. In this system, only two materials of silicon and germanium are used. The results show that the system possesses better athermal performances in the temperature range --40~C~d-60~C. The image quality of the system achieves diffractive limit. In addition, the optical system has many advantages, such as simple structure, small volume and low-cost. It can be applied to military and space infrared optical system. |
